What is 4x – 5 = 16 ? I have to show my work

Answer:

[tex]y=\frac{7}{2}x+11[/tex]

Step-by-step explanation:

To solve, we need to find the y-intercept (b). In order to find the y-intercept, we can plug in the slope and the (x,y) coordinate pair given to us into the equation to solve for the y-intercept:

y=mx+b

4=(-7/-2)*-2+b

4=14/-2+b

4=-7+b

Add 7 to both sides

b=11

Therefore the equation is:

[tex]y=\frac{7}{2}x+11[/tex] (note that the fraction is positive since the two negatives cancel out)

Answer:

Step-by-step explanation:

This is a reflection over a horizontal line.

Let's find the line by calculating the difference of the y-coordinates of corresponding points:

Answer:

Let x = salary of the architect, in thousands

Let 2x - 25 = salary of a lawyer, in thousands

2x + 2x - 25 = 206 (combined salaries, in thousands)

4x - 24 = 206

4x = 206 - 25 = 181

x = 45.25, in thousands.

The architect earns $45,250 yearly

The lawyer earns $65,500 yearly

If you want to set up a system of equations with 2 variables.

Let x = the salary of the architect, in thousands.

Let y = the salary of the lawyer, in thousands.

x + y = 206

y = 2x - 25

Solving by substitution will yield the same equation as above: x = 45.25 or $45,250

Then y = 2(45,250) - 25,000 = $66,500

Cubic, f(x)=x^3

Quadratic, f(x)=x^2

Square root, f(x)=√x

Constant, f(x)=c

Linear, f(x)=x

Step-by-step explanation:

The domain of the square root parent function is x ≥ 0 as the square root of only non-negative values exists and that of negative values does not exist, while the domain of the cube root parent function is the set of all real numbers as the cube root of all numbers exists.

A function is a relation between a dependent variable f(x) and an independent variable x, where for every value of x in its domain, there is one and only one value of f(x).

The domain of a function is the set of values of x, for which f(x) exists.

The range of a function is the set of values of f(x), in a given domain of x.

We are asked why is the domain of the square root parent function x ≥ 0 and the domain of the cube root parent function all real numbers.

We know that the domain of a function is the set of values of x, for which f(x) exists.

Let the square root parent function be f(x) = √x.

The domain of this function is x ≥ 0, as the square root of negative values does not exist in the real number system.

Let the cube root parent function be g(x) = ∛x.

The domain of this function is all real numbers, as the cube root of all values does exist in the real number system.

∴ The domain of the square root parent function is x ≥ 0 as the square root of only non-negative values exists and that of negative values does not exist, while the domain of the cube root parent function is the set of all real numbers as the cube root of all numbers exists.

Step-by-step explanation:

y = 10sqrt(5) from the pythagorean theorem

The angle opposing z is arctan(2)

So, find z by the equation

z/y = tan(arctan(2)) = 2

z = 20sqrt(5)

And finally, find x by the pythagorean theorem

x = sqrt(1600) = 40

Answer:

20,000

Step-by-step explanation:

We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.

\

Answer:

the company's total budget is 20,000

Step-by-step explanation:

A company spends 13% of its month budget on rent which total $2600

Let x be the month budget on rent

13% of the month budget is 2600

13% can be written as 13/100

Now we solve for x

multiply both sides by 100

divide both sides by 13

x=20000

So, the company's total budget is 20,000

Considering the definition of probability, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].

Probability is the greater or lesser chance that a given event will occur.

In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.

Then, the probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases.

[tex]P(A)=\frac{number of favorable events}{ total number of possible events}[/tex]

The probability of event A can only be a number between 0 and 1; although it can also be written as a percentage.

In this case, you know:

Replacing in the definition of probability:

[tex]P(A)=\frac{12}{ 139}[/tex]

Finally, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].

Answer:

Look at the variables and numbers in the equation, and what it equals

Step-by-step explanation:

Expressions that are the exact same have infinite solutions

[tex]5x+3=5x+3[/tex]

Expressions that are different have 1 solution

[tex]6x+7=5x-2[/tex]

Expressions that are the same with different operands have no solution

[tex]5x-3=5x+3[/tex]

Explanation:

The short of it is that when the equations are in the same form, if one equation is the same as or a multiple of the other, there are infinite solutions. If one equation is the same as or a multiple of the other, except for the constant terms, there are no solutions. Otherwise, there is one solution.

Example:

If one equation is x +2y = 3, then you can consider the other equation:

  3x +6y = 9 . . . . 3 times the first equation: infinite solutions

  3x +6y = 6 . . . . 3 times the first equation; constants differ: no solutions

  3x -6y = 9 . . . .  not a multiple of the first equation: one solution

Here's a more formal method.

Put both equations of the linear system of two equations into general form:

  ax +by +c = 0

  dx +ey +g = 0

Perform the following arithmetic:

  p = ae -db . . . . . this is called the system "determinant"

  q = bg -ec

  r = cd -ga

If p = q = r = 0, the equations describe the same line, so there are infinite solutions.

If p = 0 and either of q ≠ 0 or r ≠ 0, the equations describe parallel lines, so there are no solutions.

If p ≠ 0, there is one solution: (x, y) = (q/p, r/p).

_____

Additional comment

This method can always be used to find the solution to a system that is known to have one solution. It often requires fewer arithmetic operations than other solution methods. It is a variation of what is sometimes called the "cross multiplication method."

Answer:

420 miles after lunch

Step-by-step explanation:

Day 1 is 630 miles travelled - total amount of travelling.

After lunch is twice the amount of m.

Twice means 2.

So,

2xm + m (they'd have travelled) = 630 total miles

(2xm = 2m & 1m is the same as m)

2m + 1m = 630

3m = 630

÷3

m = 210 miles

Initial miles travelled before lunch was 210.

After lunch is double that amount.

Thus, 210 x 2 = 420 miles

Check:

210 + 420 = 630 miles.

Answer:

[tex]\huge\boxed{\sd -9, \ 1}[/tex]

Step-by-step explanation:

Given quadratic equation is:

x² + 8x - 9 = 0

Using mid-term break formula

x² + 9x - x - 9 = 0 (When we multiply middle terms, we get side terms as answer which is mid term break formula.)

Taking common

x(x + 9) - 1(x + 9) = 0

Take (x + 9) common

(x + 9)(x - 1) = 0

According to zero's method:

Either:

x + 9 = 0      OR    x - 1 = 0

x = -9           OR       x = 1

Answer: 12 and 8

Step-by-step explanation:

The integer m whose factors are 15,12,10 and 6 is 60 and 8 is not, therefore, for integer 60, 8 will be not the factor so option (D) is correct.

An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.

Integer ; ....-2 , -1 , 0 , 1 , 2 , .....

Integers are non-decimal numbers and all integers are rational numbers.

The factors of 10 ⇒ 2 × 5

The factors of 12 ⇒  2 × 2 × 3

The factors of 10 × 12  ⇒  2 × 5 × 2 × 2 × 3

We can make all factors by 2 × 5 × 2 × 2 × 3 like 5 × 3 = 15 , 2 × 2 × 2 = 8.

So find a number whose all will be a factor except one.

The factor of 60 ⇒ 2 × 2 × 3 × 5

We cannot make 8 by this factor but can make 15,12,10,6.

Example 15 = 3 × 5 , 12 = 2 × 2 × 3

Hence "The integer m whose factors are 15,12,10 and 6 is 60 and 8 is not, therefore, for integer 60, 8 will be not the factor".
